Note: For windows 7 desktop users you’ll need to install the active directory modules for powershell by following the installation steps herehttps://www.microsoft.com/en-gb/download/details.aspx?id=7887
A better version could be to filter the process for explorer.exe
Get-WmiObject -class win32_process -Filter "name = 'Explorer.exe'" -ComputerName MACHINENAME -EA "Stop" | % {$_.GetOwner().User}
Or if you wish to resolve down to the actual full person's name
Get-WmiObject -class win32_process -Filter "name = 'Explorer.exe'" -ComputerName WDUKLON-0102 -EA "Stop" | % {Get-AdUser -Identity $_.GetOwner().User | Select -Property Name}
For all logged on users though, use the following script…
